Documentation

Edit and format any plain text directly in the browser using a single workspace that combines real-time statistics, find and replace, transformation tools, and persistent auto-save. Type or paste content into the main editing area and use the built-in tools to transform, search, analyze, and export your work. Every change is saved automatically to your browser storage, so your text remains intact even after closing the tab or refreshing the page. No account or installation is required.

  • Type or paste your text into the main text editing area at the top of the page. The editor accepts any plain text content, from short notes to full documents.
  • Monitor your text statistics in real time. The Statistics section updates automatically and displays character count (with and without spaces), word count, sentence count, paragraph count, and line count.
  • Use the Find and Replace section to search for specific words or phrases. Enter your search term in the Find field and an optional replacement in the Replace with field. Enable Case sensitive for exact matching or Use regular expression for advanced pattern matching. Click Find Next to locate occurrences, Replace to replace the current match, or Replace All to replace every occurrence at once.
  • Apply text transformations using the Transform Text buttons. Convert text to uppercase, lowercase, title case, or sentence case. Use Trim Lines to remove leading and trailing whitespace from each line. Remove empty or duplicate lines, sort lines alphabetically in ascending or descending order, reverse the line order, or add and remove line numbers.
  • Click Copy to Clipboard to copy the full text for pasting elsewhere. Click Download as .txt to save your text as a plain text file. Customize the filename in Settings.
  • Open Settings to adjust the download filename, toggle auto-save, or enable and disable word wrap in the editor area.
  • Click Reset to clear all text and restore the editor to its default empty state.
  • Press Ctrl+Z (or Cmd+Z on Mac) to undo recent changes, including transformations, find and replace, paste, and reset. Press Ctrl+Y or Ctrl+Shift+Z to redo. Undo history covers programmatic edits that the browser's built-in undo cannot reverse.
  • Share a pre-filled editor by appending URL query parameters. Use ?t=your+text+here to pre-populate the editor with specific content when sharing the link.

Apply this editor to a wide range of practical workflows for writers, developers, students, marketers, and anyone who works with text. Each scenario below describes a specific way the editor adds value to common tasks.

  • Writing and Drafting: Draft blog posts, articles, emails, or notes in a distraction-free environment. The auto-save feature ensures that no work is lost during a writing session, even if the browser is accidentally closed.
  • Data Cleaning: Paste a list of items copied from a spreadsheet or database and use the transformation tools to remove duplicates, trim whitespace, sort entries, or remove empty lines. Prepare clean data for import into other systems.
  • Content Editing: Use Find and Replace with regular expression support to perform advanced search and replacement operations across large blocks of text. Correct repeated typos, reformat patterns, or standardize terminology in a document.
  • Code and Configuration: Edit plain text configuration files, code snippets, or log files. Use line numbering to reference specific lines and sort or deduplicate entries in lists or configuration blocks.
  • SEO and Marketing: Prepare keyword lists by pasting raw data, removing duplicates, sorting alphabetically, and trimming unnecessary whitespace. Monitor character and word counts to stay within platform limits for meta descriptions, ad copy, or social media posts.
  • Education: Track word and character counts to meet essay length requirements. Apply the transform tools to prepare example text or format student submissions consistently.
  • Quick Formatting: Convert pasted text to a consistent case format before inserting it into a presentation, document, or form. Title case conversion is useful for headings, while sentence case normalizes text copied from all-caps sources.
  • Collaboration: Share a pre-filled editor link using URL query parameters to send colleagues a starting template with predefined text, enabling consistent collaborative workflows.
